I have irregular periods due to being overweight oily hair and skin bloating fatigue gas dizzy when standing up or laying down are these signs of pregnancy?

It is not possible for us to determine whether or not you are pregnant based on the symptoms you have mentioned. Pregnancy symptoms can vary from person to person, and some of the symptoms you have described can be associated with other conditions unrelated to pregnancy. For example, irregular periods can be caused by a number of factors, including thyroid issues, hormonal imbalances, or polycystic ovary syndrome (PCOS). Oily hair and skin, bloating, fatigue, and gas can all be caused by dietary choices, stress, or hormonal imbalances. Dizziness when standing up or laying down can be a symptom of anemia, low blood sugar, or dehydration.

The only way to know for sure if you are pregnant is to take a pregnancy test. Pregnancy tests are available over the counter at most pharmacies. If you have any concerns about your symptoms or if you suspect that you might be pregnant, it is important to see a doctor for a professional evaluation.
